ELM88xxxxA CMOS 300mA LDO Voltage regulator
http://www.elm-tech.com
■General description
ELM88xxxxA is high current and low dropout(LDO) CMOS fixed voltage regulator. There are 2 types of CE
selection for ELM88 series: non-chip enable function and “H”active. Thermal shutdown protective function and
short circuit current limiter are included in the IC. The standard output voltages are 1.2V, 1.8.V, 2.5V, 3.0V, 3.3V,
5.0V; ELM88 series can also be designed as semi-custom IC within the range of 0.8V to 5.0V by 0.1V step.
